Yes we can. At least for the commercial broadcast stations in the USA.
AM stations:
Carrier frequencies are at every 10 KHz, between 550 KHz and 1700 KHz.
FM stations:
Carrier frequencies are at every 0.2 MHz, between 88.1 MHz and 107.9 MHz.
In the USA: All commercial AM stations are assigned frequencies in the band 550-1620 KHz, in increments of 10 KHz. All commercial FM stations are assigned frequencies in the band 88-108 MHz, in increments of 100 KHz (0.1 MHz).
Some popular Mexican radio stations are Radio Formula FM 104.1, Los 40 Principales MX, Stereo 97.7 and Alfa Radio. All radio stations are located in Mexico City.
When you listen to the radio, your receiver is tuned to a specific frequency, allowing it to capture and decode the signal from that particular station. Radio stations broadcast their signals on different frequencies, and the receiver selectively amplifies the signal from the chosen frequency while filtering out others. This selective tuning is made possible by the design of the radio's circuits, which isolate the desired signal and suppress interference from other stations. As a result, you can enjoy clear audio from just one station at a time.

93.5 is simply the frequency that the station transmits at. Dozens of stations can use this same frequency around the country. In the Related links section below is a resource to find radio stations near where you live. Enter your zip code, and it will display a list of nearby stations and their frequencies.

The only way your radio has of separating one station out of the pile, and letting you listen to the one single station you want to hear, is by frequency. If two stations are on the same frequency, then your radio hears them both when it's tuned to that frequency. If there are 100 of them, you hear all 100. The result of that is . . . well, just listen to CB some time.
Radio waves have the longest wavelength and the lowest frequency among all types of electromagnetic waves. They are used in communication and are emitted by sources like radio stations and cell phones.
Because different radio stations broadcast at different frequencies, and the radio tuner lets you decide which frequencies to listen to. Radio station owners have to buy the rights to use a particular frequency within a particular area. When you are driving sometimes you will hear two stations overlapping as you move out of the range of one station and into the range of another that is broadcasting on the same frequency.
Yes, resonance can work in tone detection. You tune the resonant circuit to the frequency you want to detect and follow it with an amplitude detector. Amplitude above your design threshold value means there is signal frequency within your passband. This is how the original crystal radio worked. The resonant frequency was the frequency of the radio station desired. All other frequencies (radio stations) were rejected by the bandpass filter.

AOL Radio offers many different radio stations. AOL Radio has over one hundred fifty stations that play all kinds of different music generas. AOL Radio started in 2001.
All radio stations must keep logs for the FCC by law...and offer Proof of Performance if needed. All public music users (radio, tv, stadiums, restaurants, clubs, etc.) have to license with royalty collection agencies like ASCAP or BMI. Terms of their agreements vary depending on size and frequency of use.
All stations are fed into the radio by the antenna. The IF filters narrow the bandwidth down to the size of just one channel
